Title: Temp. dependent regulating valve - has solenoid valve controlled by operation amplifier with RC time constant stage
Inventor: ORTLINGHAUS ULRICH DIPL ING
IPC: G05B11/26
Filed: 1976-09-23
Abstract: A switching regulator that responds to temperature uses RC smoothing elements so as to minimise variations due to the capacitive component. The supply transformer (2) output is rectified by a bridge circuit (3) and this has an associated smoothing capacitor (4). A variable resistor (11) and a temperature dependent resistor (14), determine the reference and feedback values for comparison in an operational amplifier (17). The amplifier controls the solenoid valuve (19). Associated make (7) and break (18) contacts switch in a transistor stage (10) with an RC time constant stage (5, 6).

Title: Safety valve for multiway pneumatic cycles - e.g. for braking system of heavy goods vehicles, gives visual warning of fault
Inventor: RITTER HANS-JUERGEN DIPL ING
IPC: B60T17/22
Filed: 1976-09-27
Abstract: Safety valve is for use with multiway cycles of pneumatic braking systems of heavy goods vehicles. The base (7) of the valve is a rectangular block with an inlet and four outlets to the braking system. Each outlet is connected to a short vertical tube and the tubes are arranged around a central hole communicating with the inlet. A flexible diaphragm (10) loaded by a spring (17) seals off the outlets from the inlet. When the air supply pressure is sufficient the spring guide (12) is pushed upwards until the groove (13) is in line with the switch button (19), and the switch operates a warning light. When the pressure falls in any cycle the switch is operated in teh reverse sense.

Title: Resistance seam welding machine using electrode rollers - suitable for cladding machine parts with wear resistant strip
Inventor: KOMAROV VLADIMIR G
IPC: B23K11/06
Filed: 1976-12-16
Abstract: Resistance-roller seam welding machines uses two electrode rollers, one of which being elastically pressed towards the other. One workpiece(a) rests on a rotary table between the electrodes, while a drive unit feeds a strip cladding material (b) stepwise from a spool through a guide and between the electrodes, so strip (b) is welded onto piece (a). Between the drive unit and the strip guide is a clamping unit triggered by a limit switch actuated by a cam on the rotary table. The limit switch is operated when the desired length of strip (b) has been welded onto piece (a), so the strip breaks at the end of the welded zone, i.e. at the hottest and weakest point. Used in mass prodn., e.g. of agricultural machinery, where a wear-resisting material (b) is welded onto machine parts; or for the mfr. of bimetallic prods.

Title: Torsional vibration damper measuring - using photocells receiving reflected light from normally aligned patterns on hub and inertia member
Inventor: BREMER JUN ROBERT CHARLES
IPC: G01L3/24
Filed: 1977-01-14
Abstract: The apparatus and methods are used for determining the response and performance of a torsional vibration damper. Normally aligned optical patterns are placed on an axial face of the hub and on an axial face of the inertia member. Light is projected on and reflected from both the pattern on the hub and the pattern on the inertia member. Displacement of the hub and inertia member and the phase relationship between the displacements is sensed during rotation by reflected light passed to two photocells. The performance of the damper, including its dynamic response, is computed by comparing the outputs of the two photocells and may be read by meters.

Filed: 1977-04-01
Abstract: The manometer has a flat working profile and employs a pressure monitoring capsule, carried by a frame, which is coupled via a pivoted lever to a pointer rotating relative to a pressure dial. The lever is pivoted at a point near its end furthest away from the dial and is coupled to the carrier for the pointer via a coupling pin which fits into a slot in the carrier, so that the pin moves along the slot as the carrier moves parallel to the pressure dial comprises a lever arm. The opposite end of the lever which has a slot into which fits a pin carried by a bar, which moves in response to the pressure monitoring capsule. The latter is adjustable in a direction parallel to the lever arm when the pointer is at the initial end of the dial.

Title: Conversion of physiological mechanical energy into electrical signals - using transducer having high polymer foils with piezoelectric characteristics
Inventor: HAEUSLER EBERHARD PROF DR RER
IPC: G04C10/00
Filed: 1977-06-29
Abstract: A transducer is used for the conversion of physiologically produced mechanical energy into electrical energy. Part of the mechanical energy produced by the heart muscles results in a pulsating expansion of the arteries which is then converted into electrical energy. The transducer is made from high polymer foils with Piezo electric characteristics. The expansion of the high polymer foil is caused by the reversable deformation of the body organs. The power can be supplied by heart pace makers, by measuring sensors inside the body, or release mechanisms inside the body. The power can also be supplied by external instruments such as that of an electronic watch.
Patent DE-2733780-A1 (DE)
Title: Automatic electrical curve tracer - uses pulse-width modulator and switching to set knee-point coordinates of polygon
Inventor: BECKMANN DIETER DIPL ING
IPC: G01D3/02
Filed: 1977-07-27
Abstract: The curve tracer comprises a selection circuit to which the knee-point voltages are fed via potentiometers. The input voltage (Ue) of the curve tracer is also fed to this circuit which compares this with the abscissae (Ueo-Ue7) of all knee-points (Ko-K7). The input is also taken to a pulse-width modulator which has a control unit which converts the input voltage into a switching signal whose mark-space ratio varies with the amplitude of the curve tracer input voltage. The switching signal is fed to a changeover unit (32) and controls coupled switches. The output from these switches is smoothed (33) and the final output is the output voltage (Ua) of the tracer. The curve tracer produces the required curve by successive approximations to straight line sections and to determine the relationship between input and output voltage, needs only to set the coordinates of the individual knee-points of the polygon course.

IPC: C21B5/00
Filed: 1977-08-20
Abstract: In the redn. of e.g. iron ores, in which an ore mixt. and a reducing agent such as a mixt. of coke and fuel oil is heated and part of the reducing agent is burnt by introducing oxygen, the fuel oil is a pyrolytic oil such as is formed in thermal or catalytic cracking of crude oil fractions. The oil serves as carbon carrier during the redn. of the ore. The pyrolytic oil suitable for the redn. of ores pref. has a viscosity of 50-700 cSt (at 50 degrees C.), a density of 0.8-1.2 g./cm.3 and S content of 0.2-6 wt.%. The oil is pref. used at a rate of 150 kg./t. pig iron. Method is economical as the heavy fraction in the cracking of crude oil fraction is utilised without further investment costs. The purification of combustion gases when using this fraction for other heating purposes is no longer necessary.

Title: Activated sludge sewage treatment - by tubular aerators under shroud in annular basin
Inventor: GASPAREC DRAGUTIN DIPL ING
IPC: C02F3/20

Title: Automatic quality control during electric resistance welding - used e.g. to avoid welding defects when making electric connections to solar cells
Inventor: WANDEL GERNOT DR
IPC: B23K11/25
Filed: 1978-01-11
Abstract: Welding defects are prevented by measuring the welding current (I) at a high repetition rate during a welding pulse, and feeding the values (I) into a digital memory. At the end of the pulse, the current integrals are calculated for the total time (Itt) and for two or more equal fractions (Ift) of the total time. When the ratio of the fractions (Ift) deviates from a prescribed value, the welding process is stopped while the welding electrodes are polished, wet cleaned, and dried. In the pref. welding appts., the current generator includes a controller fed with the actual voltage (UUist) and a desired reference voltage (Usoll), the latter being supplied from a digital processor fed with values (I) from an analogue/digital converter. Used e.g. in the microwelding of electric connections on semiconductor elements used in mfg. solar cells.
